No. 3,166,564 and further described in J. Med. Chem. 14, 772 (1971) i.e.', by reacting an appropriate substituted thiocarbamoyl chloride with an alkali metal or ammonium thiocyanate to form the corresponding substituted thiocarbamoyl isothiocyanate and then reacting the latter with an appropriate secondary amine.
The salts of these compounds can be prepared by mixing an equimolar amount of the desired acid or an equimolar amount of the desired base with the appropriate dithiobiuret in a suitable solvent.
The following examples are given to illustrate the above-described processes. All parts are by weight unless specified otherwise.
EXAMPLE 1 Preparation of 1 l -dimethy1-2-thio-3-[(4-propylpiperazinl-y1)- thiocarbonyl]urea A solution of 12 parts of N-propylpiperazine in 50 parts of acetone was added dropwise to a solution of 14.2 parts of dimethylthiocarbamoyl isothiocyanate in 100 parts of acetone at to 15C. The solution was then allowed to warm to room temperature, stirred for approximately 2 hours, and then filtered.
The solvent was removed under vacuum and the residue dissolved in 50 parts of 10% sodium hydroxide. The aqueous solution was washed twice with 50 parts of chloroform and then acidified with glacial acetic acid to about pH 7. The acidified solution was then extracted twice with SO-part portions of methylene chloride. The hydrocarbon layers were combined, dried over anhydrous magnesium sulfate, filtered, and the solvent was then removed under reduced pressure to give 13.5 parts of l,l-dimethyl-2-thio-3-[(4- propylpiperazin-1-yl)-thiocarbonyl]-urea as a viscous oil.
EXAMPLE 2 Preparation of l,1-dimethyl-2-thio-3-[N-(Z-dimethylaminoethyl)-N- methyl-thiocarbamoyl]urea A solution of 10.2 parts of N,N,N-trimethyl ethylene diamine in 20 parts of acetone was added dropwise to 14.2 parts of dimethylthiocarbamoyl isothiocyanate in parts of acetone at l015C. The solution was allowed to warm to room temperature, stirred for an additional 2 hours, and then filtered.
The solvent was removed under reduced pressure and the residue was dissolved in a mixture of 100 parts of chloroform and 50 parts of 10% aqueous sodium hydroxide solution. This mixture was shaken and then separated. The aqueous layer was acidified to about pH 7 with glacial acetic acid and then extracted three times with 50 part portions of methylene chloride. These extracts were combined, dried over anhydrous magnesium sulfate, filtered, and the solvent was removed therefrom under reduced pressure to give 13 parts of the crude product. Crystallization from ethanol gave 5 parts of pure l,1-dimethyl-2-thio-3-[N-(2- dimethylaminoethyl)-N-methyl-thiocarbamoyl]urea, m.p. 9394C.
EXAMPLE 3 Preparation of l, l-dimethyl-2-thio-3-[N-(3-dimethylaminopropyl)-N- methyl-thiocarbamoyl]urea A solution of 11.6 parts of N,N,N'-trimethyltrimethylenediamine in 30 parts of acetone was added dropwise to 14.2 parts of dimethylthiocarbamoyl isothiocyanate in 100 parts of acetone at 1015C. The solution was allowed to warm to room temperature and then stirred for an additional hour.
The solvent was removed under reduced pressure and the residue was recrystallized twice from ethanol to give 3.2 parts of crystalline 1,1-dimethyl-2-thio-3- [N-(3-dimethylaminopropyl-N-methylthiocarbamoyl1urea, m.p. l08-1 10C.
EXAMPLE 4 Preparation of 1,l-ciimethyl-2-thio-3-[(4-methylpiperazin-1-yl)- thiocarbonyl]urea A solution of 100 parts of N-methylpiperazine in 100 parts of acetone was added dropwise to 142 parts of dimethylthiocarbamoyl isothiocyanate in 650 parts of acetone at l0l5C. The resulting solution was allowed to warm to room temperature and stirred for 16 hours, during which time a solid precipitated. The solid acetic acid salt of l,l-dimethyl-2-thio-3-[N-(3- dimethylamino-3-methylpropyl)-N-methylthiocarbamoyl]urea acetic acid salt of l,l-dimethyl-2-thio-3-{N-[2- (pyrrolidinl -yl)- l -methylethyl]-N-methylthiocarbamoyl}urea nitric acid salt of l,l-dimethyl-2-thio-3-{N-[3- (azacycloheptl -yl l -methylpropyl]-N-methylthiocarbamoyllurea EXAMPLE 6 Preparation of the sodium salt of l, l -dimethyl-2-thio-3-[(4-propylpiperazinl -yl thiocarbonyl]urea 0.8 Part of sodium hydroxide is added to a solution of 5.5 parts of l, l -dimethyl-2-thio-3-[(4- propylpiperazin-l-yl)-thiocarbonyl]urea in 50 parts of water. The resulting mixture can be stirred until all the solid is dissolved to give an aqueous solution of the desired sodium salt of l,l-dimethyl-2-thio-3-[(4- propylpiperazinl -yl )-thiocarbonyl ]urea.
By using an appropriate base with an appropriate dithiobiuret, the following salts can be prepared similarly:
sodium salt of l,l-dimethyl-2-thio-3-[(1,2,2-
trimethylhydrazino )-thiocarbonyl ]urea sodium salt of 1,1-dimethyl-2-thio-3-[ (1,2,2-

The resulting slightly cloudy yellow solution is then filtered to remove impurities thereby affording 48 parts of a 17% aqueous solution of the triethanolamine salt of l,l-dimethyl-2-thio- 3-[(4-methylpiperazinl -yl )-thiocarbonyl urea.
